Spends too much time on here
FYI - Posts #2 and #14 on this thread say they have both.
I just looked at the 2020 brochure and it says it's not available with air suspension. Fixed (MXA) is Active (MXB) isn't.
If OP can provide his build sheet than we can confirm.
Maybe confusing active grille shutters and active air dam. They haven't got a 2020 with air suspension at my local dealer so I can't crawl under it and confirm.
